Jay Hamilton is the main antagonist of the 2004 remake, Walking Tall. He was portrayed by Neal McDonough, who also portrayed Damien Darhk. He's a corrupt businessman and drug lord, who was Chris Vaughn's best friend now turned arch enemy.
He owns a little town in Kitsap County, Washington and opens a casino, which has to do with a lot of income for the town. He was Chris Vaughn's, the hero and ex army sergeant's, old friend, who gives him an invite to his casino for a good time, which results in Vaughn getting into a fight and knocked unconscious. When Vaughn recovers, Hamilton offers him a job and money, which Vaughn turns down. Then his nephew tries crystal meth, which he got from Hamilton's henchmen and Vaughn fights his security guards.
Hamilton uses and pays Vaughn's lawyer to take a deal and keep him quiet, which results in Vaughn firing his attorney and his charges dropped. When Vaughn becomes the new sheriff, He pulls over Hamilton, who reminds him of his past failures and future failure with being a cop. Later Hamilton orders Vaughn's truck destroyed and the killing of Vaughn himself and his friends and familu. But even though Vaughn's truck gets blown up, Vaughn defeats Hamilton's henchmen with the help of his girlfriend, friends, and family.
Vaughn hunts Hamilton down at a mill, where his drug lab is also, and fights one on one with Hamilton. After beating Hamilton, Hamilton has the courage to spit in Vaughn's face, telling him he's nothing which prompts for Vaughn to break Hamilton's leg with an uprooted 2x4. Vaughn rethinks about what Hamilton said earlier in the film, and tells Hamilton that it does change their relationship, it's Vaughn's town and that Hamilton is going to jail for a long time.
